ELEVATOR VENTILATION Application filed December 10, 1930. Serial No. 501,170.

This invention relates to the ventilation of elevators.

For fire and other safety reasons, elevator cars at the present time are usually closed 5 in about the sides and top. Because of this fact, the ventilation is usually poor and the electric fans which are now sometimes installed in these closed elevator cars can only partially alleviate these conditions.

It is the purpose of the present invention to secure a proper ventilation of closed elevator cars and to accomplish this in a simple practical fashion.

Special features of the invention whereby are attained are the provision of louvers, grllles or ventilating openings in the walls of the car and deflectors operable in the trav- 7 el ofthe car to direct air in through the trating the upper wall portions of an ele-.

vator car and showing an embodiment of the invention incorporated therewith; Fig.

2 is a broken outside view of the elevator car showing the ventilator controls on different sides of the car and in difierent operative positions; Fig. 3 is a combination sectional view illustrating a modification.

' Insomuch of the elevator car asis illustrated, the side, back and top walls are indicated at 3, 4 and 5 respectively and cupped ornamental ventilating grilles 6 are shown set in the side and back walls, near the top and close below the ceiling or root of the car. These grilles or screens may be of any desired ornamental or other shape, but the inwardly and upwardly cupped design shown has the advantage that all entering air is deflected up toward the ceiling of the car, so that there can be no direct drafts or blasts structure is shown as having an inset 7 Overthe foregoing and other desirable objects ventilating openings. These deflectors may, be in the nature of vanes or scoops and may on the passengers in the car. The ceiling standing the upwardly directed mouths of the grilles serving as a deflector, to diffuse, break the force and direct the air currents down in the passenger space in the car. The location of these ventilating openings how-' ever may be varied and they may for in stance, be set at different levels, even, ifidesired, down near the floor of the car.

The deflectors governing the inflow of air are shown at 8 in the vform of vanes pivoted midwidth at 9 in suitable brackets 10 and ofiset sufliciently from the walls of thecar to operate as well defined scoops when tilted in one direction or the other.

The tilting of the vanes is efi'ected in the illustration by providing the same adjacent their pivotal centers with inwardly projecting rockerarms 11 and suitablemechanical connections for swinging the same one way or the other. 1 3

Automatic reversal of the vanes is effected in the illustration by electro-magnets 12 in the form of solenoids having magnetic cores 13 connected by rods 14 and pivoted links 15. with the rocker arms of the vanes. These electro-magnets may be so connected with the reversing lever or control of the car, as indicated at 23, Fig. 1 that when the car travels downwardly the solenoids will be energized to swing the vanes inwardlyat the top and out at the bottom as in Fig. 1, to scoop the air in through the grille in the downward travel of the car andto swing the vanes as shown at the right in Fig. 2 to scoop in the air in the upward travel of the car. Inthis latter view, the vane which appears in elevation atthe back of the car is shown reversed, that is closed at thetop and open at the bottom, so as, to induce an outflow of the air at Means by which the vanes or deflectors may be secured in various positions, 'or be operated independently of any automatic con-- trol, are shown in the form of hand slides 16 inside the car guided in brackets 17 and connected at the top by pivoted links 18 with the rocker arms 11, said links being angled as indicated to extend out through slots 1 in the grille work to the vane shifting arms.

Spring plungers or the like may be provided for restraining and yieldingly retaine ing these hand slides as indicated at 20, the same cooperating with notches 21 in the slides corresponding to the fully tilted and intermediate positions of thevanes.

-- If desired,v means for positively locking the slides and hence the vanes may be provided such as the lock screws indicated at 22 in the upper guide brackets, designed when operatedto grip and hold the slides and conse quently the vanes in any desired relation. 7

With the operating and controlling means disclosed, it will be evident that the vanes may be automatically or manually shifted, or some be automatically and others hand controlled and some or all may be secured in various relations, to best suit different requirements, The automatic reversal of the vanes also may be effected by thereversal of the air force,which results when the movement of the car is changed from one direction to the other.

In some cases, the inflow of air may be effected; automatically by means of scoops such as shown at 664 and 6b in Figure 3, the same forming part of the grille work, pressed outwardly of thecar; the first mentioned, facing upwardly and taking in air on the upward movement of the car, and the second mentioned, facing downwardly. to take in air on the downward Tmovement of the car. These scoops are shown as arranged alternately in upwardly and downwardly facing relation and as relatively, small and closely spaced,but they may be arranged in groups of a kind instead of alternately, and they may be spaced m varlous ways and made in larger or smaller sizes, depending on various conditions, such as size andspeed of the car, ex-

' tent of travel, etc. The scoops or ventilation having walls with a ventilation opening 0 7.

openings therein, air deflecting means positioned to direct air into the car through said ventilating opening or openings in the vertlcal travel of the elevator and means for reversing said air deflecting means to render the same effective in the upward or in the downward travel of the car. 7 V

3. In elevator ventilation, an elevator car having walls with a ventilation opening or openings therein, air deflecting means positioned to direct air into the car through said ventilating opening or openings in the vertical travel of the elevator and means for automatically reversing the efiective operation of said air deflecting means upon the reversal of vertical travel of the elevator 4. In elevator ventilation, an elevator car having walls with a ventilation opening or openings therein, air deflecting means pos'i-- tioned to direct air into-the car through said ventilating opening or openmgs 1n the vertioal travel of the elevator, automatic means for reversing said air deflecting means upon.

reversal of the direction of travel of the car and means for arbitrarily controlling said air deflecting means independently of such automatic control.

5. In elevator ventilation, an elevator car having walls with ventilation openings therein, vanes governing admission of air into. different openings and means for arbitrarily.

setting the diiferentvanes at different selected angles. i

6. In elevator ventilation, an elevator car having walls with ventilation openings there-1 in, a vane horizontally pivoted over the out-:

side'of said ventilation openings and means for shifting the vane at its pivotal support to vary the air deflecting action. produced by said vanein the up and down travel in the elevator car.

7 In elevator ventilation, an elevator car having walls with ventilation openings therein, a vane horizontally pivoted over the oute slde of said ventllatlon openlngs, means forshifting the vane at its pivotal support to vary the air deflecting action produced by said vane in the up and down travel in the elevatorcar, the pivotal mounting of the vane being approximately midwidth the vane and the vane being shiftable to opposite angular positions to enforce an inflow of a'ir'in the upward travel m one position and m;

the other-positionto enforce an inward flow on the downward travel of the car.

8. A combination as-in claim 7 with.

means for holding the vane in an intermediate relatively inactive position.

9. The combination as in claim 7, in

which the shifting means'is automatically operable in the reversal of travel of the 618-.

vator car and in which arbitrarily operable means are provided for setting the vane in different selected positions.

12. An elevator car having upwardly and downwardly facing air scoops in the sideof the same.

In testimony whereof I afiix my si nature.
